If a car travels 480 miles in 6 hours, what is its average speed?

To find the average speed of the car, you can use the formula for average speed, which is total distance traveled divided by total time taken. In this scenario, the car has traveled a total distance of 480 miles over a span of 6 hours.

The calculation for average speed is as follows:

Average Speed = Total Distance / Total Time

Substituting in the values gives:

Average Speed = 480 miles / 6 hours

Calculating this results in:

Average Speed = 80 miles per hour.

The correct answer is 80.0, which matches choice B. This represents a straightforward calculation of distance divided by time, leading to the average speed for the trip.

Understanding how to compute average speed using this method is essential in problems relating to motion, as it provides a clear and direct approach to determine the rate of travel over a distance within a given timeframe.
